purenit – a diamond among smart materials2

purenit – what’s it all about?The answer is quite simple: purenit is a high-density smart material combining an incredulous multitude of outstanding properties. purenit performance data can be termed brilliant without any qualifica-tion. purenit is a polyurethane product on a (PUR/PIR) rigid foam basis providing a high thermal insulation value. Its bulk density ranges around 550 kg/m3 – and this makes purenit a genuine light-weight – despite all its rigidity, stability and high thermal insulation value.

purenit – the incredible smart material!If you intend to point the way by means of performance, you need a reliable basis to safely realize your own ideas and developments. New ways frequently require also new materials and their com-bination. However, what do you do, if traditional materials have reached their limits? If wood, metal, plastics or any other composite material do not meet your very special requirements? This is the point where purenit comes in – the innovative construction material that simply offers more possibilities!

Brand quality from one source.purenit is a brand product. Remainders from the polyurethane manu-facture of puren’s are integrated into purenit – however, and this makes for the difference, no waste materials are being used for its production. Homogenous only and free of foreign substances is the motto. Therefore, all substances used in production are being strictly tested. purenit's very special properties are based on highly developed recipes of puren. And for this very reason, all substances and materials from basic raw materials up to finished purenit are directly pro-cessed by puren.

purenit – sustainability in perfection.To assess how sustainable and ecolo-gical a material really is, the complete life cycle of a product from manufacture via usage up to disposal or reuse must be considered. purenit is a product setting the pace in this direction, being an excellent example for the objective target of sustainability set by puren gmbh.

The EPD (Environmental Product Declaration) for polyurethane insulating panels explicitly refers to the manufacture of high-grade materials on polyurethane basis.

Highest demands? Then you’re exactly right with purenit.Sophisticated new solutions not only require innovative ideas but also materialsproviding a reliable basis for new approa-ches to solutions where product perfor-mance is concerned. purenit as high-per-formance smart material is a material whose range of application basically ex-pands every day. Many processors of purenit ask themselves: „Whatever did we do before purenit was available? purenit’s unique performance is no accident.

Takes a lot, has a thick skins and lasts and lasts and lasts…Extensive tests attest excellent mecha-nical properties to purenit. The material is extremely resistant to pressure as the value of 7,1 Mpas (EN 826) confirms. Therefore, purenit is highly suitable as building component or as core materialof sandwich elements. Being so resistant to pressure, it is also suitable for safe connections and applications in the installation sector.

purenit is extremely pressure-resistant as its technical properties confirm. purenit is highly suitable for building components or as core material of sandwich constructions.

purenit also resists liquid nitrogen.Moisture has an extreme impact on many materials. purenit even retains its shape in boiling water.

Solutions, solvents, agents – purenit resists a multitude of popular chemicals and is also suitable for mineral-based plaster systems.

Hot, cold, wet or moist? purenit is a genuine wonder material.Being a diffusion-open smart material,purenit excels with outstanding climatic properties. Under strain from moisture, purenit shows its extraordinary perfor-mance and distinguishes itself clearly from wooden materials. Even extreme moisture will not result in a change ofshape – not even under long-term strain. Its rather low μ-value of 8-12 positively supports water vapor permeability. Waterabsorbed is being harmlessly released. Another advantage: purenit is non-rotting, mold- and mildew-resistant and even resistant against termites – i.e. absolutely predestined for the manufacture of buil-ding components and installation work.

Unnerves physicists: purenit’s thermal behavior.As duroplastic insulation material, purenit convinces with its enormous thermal capacity, resisting short-term temperatures from –50° C up to +250° C. The thermal conductivity is around 0.087 (EN 12667) or 0.096 (DIN 4108-4) W/(mk). Naturally, purenit is an insulation material approved by the building authorities and complies – also in its reaction to fire – with valid standards.Its extremely low thermal expansion coefficient of 5 mm at 100 K over a length of 1 m greatly facilitates any combination with other materials.

purenit resists acids, solutions, solvents and other substances. purenit's expansive resistance to most chemicals and solvents, dilute solutions and acids opens an enormous range of applications. Today, trend-setting com-posite materials are mostly laminated or bonded. Like hardly any other material,purenit works well with adhesives andlaminate materials. Even without lamina-tion, purenit proves its longevity in critical and difficult application areas such as in agriculture, in particular for animal hus-bandry. Here, too, purenit sets standards and meets highest requirements.

Simple and cost-efficient processing.That purenit as smart material can take a lot is one fact, its nearly limitless variety of applications another. Here, one hears again and again: „Incredible!” purenit can be processed easily on any current wood working machinery and tools – just as you’re used to from working with chip-boards. Carbide tools will help. Remain-ders from processing may be given over

to regular thermal recycling. For screw connections, we recommend predrilling and leaving sufficient distance to the edges. During processing, purenit bis impressive in every aspect.

Bonding and laminating safely.Ever frequently, glued connections are used to interconnect parts and compo-nents. purenit allows for nearly any knownprocess. To achieve perfect bonding with

purenit, we recommend to determine the details with the manufacturer of the adhesive. purenit works extremely well with widely-used 1K- or 2K-PU adhe-sives, hotmelt or water-based adhesive systems. No problems with paints or painting withpopular products or systems that are solvent-based themselves. As with othermaterials, paint a test surface to achieveoptimum paint results.

purenit – a brilliant smart material,offering a thousand possibilities

The first all-rounder surpassing everything.Famous companies rely on the smart material purenit and appreciate the manyadvantages of this special construction material. To manufacturers of building elements, its resistance to moisture makes all the difference. In vehicle construction, it is its excellent behavior towards adhesives and the resulting multitude of surface laminates. For manufacturers of counter tops and floor elements, pressure resi-

stance and the possibility to use wood working machinery for processing are predominant. For manufacturers of lab furniture or agriculturally used products, its resistance to chemicals is the princi-pal characteristic.

Wooden materials we had yesterday, today, it’s purenit.purenit performs better than other materials and its total properties are practically without competition. Its bulk density of 550 kg/m3 makes purenit a

lightweight among smart construction materials and thus contributes to redu-ce weight for the vehicle industry, i.e. a substantial advantage for commercial vehicles and campers. The homoge-nous material structure of purenit furthermore provides excellent thermal insulation – it can hardly get any better!
